About Me

Hi I am Beili (Echo) Yin ,
As a software engineer with a strong background in backend systems and cloud infrastructure for games. With experience in C#, C++, and Python, I build scalable, reliable services and tools that empower development teams. My passion lies in creating smooth online experiences and improving developer workflows through thoughtful engineering.
Working in the game industry for sometime, I realised that toolings and automation services in game development could greatly accelerate the project productivity. Hence a series of blogs about platform engineering is in order.
